Oscillator characterization requires a wide variety of tests to fully complete — the measurement equipment stability must far exceed the oscillator under test.
With flexible, FPGA-based hardware and a reconfigurable suite of instruments, you can save time and test back-to-back in both the time and frequency domains. Built-in, real-time graphs accelerate data visualization to help you see measurements in parallel with data collection, saving time during post-processing and plotting.
Measuring time: Quantifying modern clocks and oscillators
Oscillator characterization is critical for designing and optimizing various applications, from simple electronic circuits to satellite communications. With one device, make time and frequency stability measurements while also utilizing built-in, real-time graphs for advanced analysis.
With both the Phasemeter and Time & Frequency Analyzer on a single device, you can track short-term frequency fluctuations with ultra-high precision, or make long-term frequency stability measurements and analyze histograms to characterize oscillator performance.
In applications where extremely high stability is crucial, implementing digital solutions with FPGA-based instruments eliminates DC noise from analog components, allowing you to achieve better stability with associated oscillators under test.
With on-device, lossless interval histograms and built-in Allan deviation, power spectral density, and amplitude spectral density graphs, you can analyze device performance during your experiment.
Advanced deep space applications require test equipment with the flexibility to deliver multiple instruments simultaneously and the performance to enable the development of stable, reliable hardware. Devices such as quantum sensors, including time and frequency references for deep space navigation, are essential for global positioning services. The Moku:Pro Laser Lock Box, Digital Filter Box, Lock-in Amplifier, and PID Controller help enable better research, development, and validation of these devices.
Originally formulated to assess the stability of oscillators in atomic clocks, Allan deviation and Allan variance provide a robust measure of frequency stability over varying timescales, which statistics such as standard deviation do not take into account. In this white paper, we review the mathematical foundation of Allan variance, and share how Allan variance and its related quantities serve as helpful tools for the precise analysis of time series data in oscillator characterization.
